Research

My research is combined of several fields of interest:

  1. Combinatorics in general, and, focusing on various versions of the Tower of Hanoi problem.
  2. Numeration Systems: representation of integers in number systems based on algebraic non-rational numbers.
  3. Data Bases - from the theoretical aspect.
  4. Iterative Numerical Methods - devising new methods and comparting their efficiency to other known methods.
